Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

The Combined Effect of Gas Phase and Condensed Phase Mechanisms in Flame Retardancy of Polybutylene Succinate

Journal of Vinyl and Additive Technology, EarlyView.
A combination of DOPO and APP flame‐retardants results in a V‐0 UL 94 rating. ABSTRACT In this study, we addressed the challenge of eliminating, during combustion, the flaming dripping behavior of polybutylene succinate flame retarded with ammonium polyphosphate, a key barrier to achieving a V‐0 rating in the UL 94 flammability test without excessive ...

Thermal Degradation Kinetics and Flame‐Retardant Synergy in Zinc Borate/Red Phosphorus‐Filled Thermoplastic Polyurethane Composites

Journal of Vinyl and Additive Technology, EarlyView.
The synergistic interaction between red phosphorus (RP) and zinc borate (ZnB) enhances the thermal stability and flame retardancy of TPU by forming a dense, stable protective char layer. Non‐isothermal kinetic analysis confirms a complex degradation mechanism governed by conversion‐dependent activation energy.

Evaluation Methodology, Numerical Verification and Retrofilling Procedure for Power Transformers to Ensure K‐Class Flame Retardancy and Environmentally Friendly

High Voltage, EarlyView.
ABSTRACT With increasing demands for fire safety and environmental friendliness, retrofilling transformers with alternative insulating liquids has become a growing trend. However, retrofilling power transformers remains uncertain, as more residual mineral oil compromises K‐class flame retardancy, and its impact on environmental performance has yet to ...

Enhancing Hydrophobic Stability of Silicone Rubber Insulators Under High‐Voltage Direct Current Stress Through Optimised Nano‐Fumed Silica Surface Area: A Dynamic Drop Test Study

High Voltage, EarlyView.
ABSTRACT The long‐term hydrophobic stability of silicone rubber (SiR) insulators is essential for their reliability in high‐voltage direct current (HVDC) applications. This study investigates the effect of nano‐silica fillers with varying specific surface areas (SSA = 120, 200 and 300 m2/g) and different concentrations of alumina trihydrate (ATH ...

Glove Reuse Limits in Hair Dyeing: Permeation of p‐Phenylenediamine and Aminophenols Through Natural Rubber Latex and Neoprene After Repeated Washing

Contact Dermatitis, EarlyView.
Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse
